OIL BURNER.

Application filed August 24, 1923. Serial Ito-659,033.

To all whom it may concern:

Be it known that I, J ACOB Manson, a citizen of the United States,residing in Jersey City, county of Hudson, and State of New Jersey, haveinvented certain new and useful Improvements in Oil Burners, of whichthe following is a specification. p

This invention has for its object to'provide a burner adapted for crudeoils and to atomize the oil either by mechanical action or by the actionof steam, or both. A further object of the invention is to provide anovel form of means for relieving excess pressure of the oil attheatomizing point by permitting a black flow of oil through a needle valverod forming part of the burner, and thence to a steerage compartment. Afurther object is to provide means for varying the area of oil conduitsleading to the burner opening in proportion with changes in the size ofthe opening. Further objects will hereinafter appear.

Reference will be made in this specifica tion to the which- Fig. 1 is alongitudinal sectionthrough a burner constructed in accordance with t einvention, andonthe line 1--1, Fig. 2.

Fig. 2 is a cross section on the line 2-2,

accompanying drawings, in

Fig. 3 is across section on the line 3-3,

Fig. 4 is a longitudinal section through a modified, and simplified,form of the burner. Fig. 5 is a cross section on the line 5 -5,

Fig. 4.

ig. 6 is a cross section of the burner shown in Fi 5 modified by theaddition of a third oil eed duct and controlling valve blade therefor. aFig. 7 is a view'similar to the preceding view showing in cross sectionfour oil feed ducts, and four controlling valve blades.

Fig. 8 is a diagrammatic view of a bat-' 'tery of the burners and meansfor simultaneously adjusting them.

Fig. 9 is a side elevation of the burner illustrated in Fig. 4 togetherwith a convenient form of support therefor, providing tor endwisemovement of the burner relatively to the'sup ort.

Referring to the embodiment of the invention therein shown comprises amain cyllindrical body A having an inner central 0 amber 2 threadedtoward its front end to receive thev threadig. 1 it will be seen that .asleeve 5 having a flanged end 5", the flange afl'ording a connectingmeans for the complementary flanged annular head of an adjusting sleeve6 which surrounds needle valve tube 4* and is both threaded on the tubeand in the burner casing A The two sets of threads are of difi'erentsize to effect a specific result, as will hereinafter appear. At therear end of the adjusting sleeve 6 a packing gland 7 is placed. At itsrear end the burner casing A is closed by a plug 8 threaded at 8* withinthe casin and surrounding adjusting sleeve 6, a pac in gland 9 beingemployed to seal "the outer en of the plug;

T e oil is fed from chamber 2 to the burner nozzle via oil ducts formedin the sides of the two halves of a sleeve 10, the i ducts being denotedby the letter a. They sleeve 10 surrounds the head 4 of-the needlevalve, and its two halves are separated by adjusting valve blades 11which lie adjacent the oil ducts a.

Each adjusting valve blade 11 is secured by a pin 11 to a sleeve 12surrounding and sweated upon sleeve 5. Thus the endwise adjustment ofthe adjusting valve blades is controlled by adjusting sleeve 6.

In Fig. 1 the needle valve and adjusting valve blades are in closedposition. When,

however, adjusting'sleeve 6 is rotated, both the adjusting valve bladesand the needle valve will be moved to the right from the position shownin Fig. 1, the valve blades movin faster than the needle valve. Thisresult is efiected by the fact that the threads 6 on the exterior of theadjust'ng sleeve 6 are coarser than the threads 0 by means of which theneedle valve is connected to the adjusting sleeve, and by the furtherfact that the needle valve is held against rotation by a member B .whichengages the squaredsection thereof; In their movement from the right tothe position shown in Fig. 1 the adjustin valve blades expose the frontends of the o1 ducts a and permit the flow of oil somewhat tangentiallyof the conical face 9 of the burner head thus causing a whirling motionof the oil, the oil then passing along the more restricted conicalportion ot'the burner head from which it emerges in a spray, which sprayis induced by pressure upon the oil and the mechanical action of theburner head. .The oil may be led into Oll. chamber 2 through a port 14in a plug 15- or at any other suitable point, such as the opening closedby stud bolt 16.

By means of plug 15 ready access may be had to chamber 2 for the operaton of an adjusting nut 17 which has a conlcal inner face correspondingwith the similar rear face of the sleeve 10, the front face of thesleeve 10 likewise being conical. Thus by rotating adjusting nut 17 soas to move it inwardly the two halves of the split sleeve 10 will bemoved toward the ad usting blades sothat the wallseof said blades willelleetually close the oil ducts (2 against the passage of oil exceptwhen the blades are moved rearwardly of conical wall 9 of the burnerhead.

As hereinbefore stated, my device comprises means for relieving unduepressure of the oil at the atomizing point, which pressure might tend toprevent complete atom ization by the forcing ofa core of unatomized oilthrough the oil spray, which core by its weight would fall in drops uponthe lower furnace wall. The means in question comprises the tubularneedle valve 4, 4". When the needle valve is rearwardly moved. from itsposition, Fig. 1, to permit passage of the oil about its conical head,communication will be effected between the outer portion of the head andthe inner passageway 2', leading throughout the length of the needlevalve to a pipe 18 which may communicate with a storage tank. When theflow of. oil, or the pressure of the oil becomes such that the oil isnot completely atomized, a back pressure will be created which willcarry the excess oil into passageway 11 and thence to the storage tank,as will be understood by those skilled in the art.

I have secured upon the rearward extension ofadjusting sleeve '6 a dialwheel 19 which in co-action with arrow 20 on member B will serve toindicate to the operator the exact adjustment of the needle valve andadjusting valve blades.

is hereinbefore set forth, my device comprlses means for both themechanical and steam atomization of the oil. For the urpose of steamatomization, I have provided a steam pipe 21' which extends throughoutthe lengt of the needle valve and is supported in the needle valve headby a disk 22 aving a central aperture for the passage of the same pipeand apertures on each side thereof for the passage of the oil in itsback flow. The rear end of the steam pipe com- 'upon the two halves ofthe sleevev 10 to move them toward each other, thus exerting a clampingaction upon the blades The opening and closing of the burner is thenelfected by rotation of. wheel 27 fixed upon the hollow shaft 28 intowhich the hollow needle valve 29 is threaded. Oil may baled into oilchamber 30 via pipe 31. The 011 IS led through oil ducts a." and thenceto the burner nozzle and the excess oil passes through the hollow needlevalve and thence is directed to a pipe 32- leading to a chamberindicated at 33. I

In Figs. 6 and 7, I have shown my device provided with more than two oilducts and 0.- controlling blades, providing fora greater flow of oil. InFi 9, I have shown a convenient methodo supporting the burner, thiscomprising a bracket 34 having an aperture to receive the supporti rod35, the bracket being held upon the rod fiy means of a screw 36.

In Fig. 8, I have shown means for,simultaneously operating a pluralityof the burners, the burners being indicated by G. In this case theadjusting wheel for each needle valve ,is formed as a worm wheel 36engaged by worm 37 on a shaft 38supported by brackets 39. Oil is ledfrom theburners through a main pipe 40 and branch pipes 41, and steam isled from the burners through steam pipes 42. The flow'o-f oil throughmain pipe 40 'is controlled by valve 43 having a dial wheel 44, and thead'ust'ing shaft 38 is controlled through a han wheel 45 ad acent a dialwheel 46 which indicates the exact POSltlOll of the adjusted elements.Shaft 38 is formed in sections connected by sleeves 47, so that eachworm 37 may be carried out of engagement with its appropriate worm wheel36 for manipulation and repositionin of the latter.

It Wlll e understood that, if desired, a stream of air under pressuremay be passed through steam pipe 21, as a substitution for the flow ofsteam.

4 It will be also understood that vanous modifications may be made inthe form of the embodiments illustrated in the drawings withoutdeparting from the spirit of my invention, what I claim and desire tosecure by Letters Patent being as follows .1.
